Description

Technical Field

[0001] The utility model relates to the field of adhesives, in particular to a polyphenylene sulfide high temperature resistant adhesive tape. Background Art

[0002] According to its function, tape can be divided into: high temperature tape, double-sided tape, insulation tape, special tape, pressure-sensitive tape, die-cut tape, and different functions are suitable for different industry needs. A layer of adhesive is coated on the surface of the tape to make the tape stick to the object. The earliest adhesive came from animals and plants. In the 19th century, rubber was the main component of adhesives; and now various polymers are widely used.

[0003] Chinese patent publication number CN104861889B discloses "an adhesive tape", comprising a substrate and a pressure-sensitive adhesive layer laminated on the substrate, characterized in that the substrate is formed of a fluorinated ethylene polymer, and the pressure-sensitive adhesive layer is formed of a (meth)acrylic adhesive containing a (meth)acrylic polymer. The adhesive tape of the present application has excellent anti-rebound, wear resistance, and release properties of the surface before and after wear, and can be molded and produced after about 7,000 times after use without floating or weakened release.

[0004] During the conception process, the applicant searched a large number of patent documents on the patent network. For example, Chinese patent publication number CN104861889B discloses that when "a tape" is used under high temperature, the high temperature will cause the sticky material on the tape to soften or melt, weakening its viscosity and making it unable to effectively bond or fix objects. Some tapes may deform at high temperatures and lose their original shape or structure, resulting in impaired functions and ineffective use, leading to the problem of poor performance in high temperature environments. Therefore, a polyphenylene sulfide high temperature resistant tape is proposed to solve the above-mentioned problems. Utility Model Content

[0006] Preferably, the tape body comprises a protective layer, the material of the protective layer is a polyphenylene sulfide film, and an anti-corrosion layer is bonded to the bottom surface of the protective layer.

[0011] Preferably, the bottom surface of the dust-proof layer contacts the top surface of the protective layer, and both the bottom surface of the dust-proof layer and the top surface of the protective layer are non-sticky.

[0012] It can be seen from the above technical solutions that the polyphenylene sulfide high temperature resistant tape provided in the embodiments of this specification has at least the following beneficial effects:

[0013] (1) The utility model provides a protective layer so that the main body of the adhesive tape has a certain degree of high temperature resistance, thereby preventing the adhesive material on the adhesive tape from softening or melting when used under high temperature conditions, thereby reducing its viscosity and making it unable to effectively bond or fix objects.

[0014] (2) The utility model provides an adhesive layer and an anti-corrosion layer, so that when the tape body is used in a highly corrosive environment, if the protective layer is corroded and damaged, the anti-corrosion layer can protect the sticky material and prevent the sticky material from being corroded and causing the tape body to fall off.

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Example 1

[0025] See also Figure 1-Figure 3 As shown, a polyphenylene sulfide high temperature resistant tape includes an inner core 1, the diameter of the inner core 1 is 151.5mm to 152.5mm, a tape body 2 is arranged on the surface of the inner core 1, the tape body 2 is wound on the outer wall of the inner core 1, and the thickness of the tape body 2 is 0.045mm to 0.055mm.

[0026] The tape body 2 includes a protective layer 21, the material of the protective layer 21 is a polyphenylene sulfide film, and an anti-corrosion layer 22 is bonded to the bottom surface of the protective layer 21. The polyphenylene sulfide film has a certain high temperature resistance and can protect the adhesive material underneath it in a high temperature environment. By setting the protective layer 21, the tape body 2 has a certain high temperature resistance to avoid using it under high temperature conditions. The high temperature will cause the adhesive material on the tape to soften or melt, thereby reducing its viscosity and making it unable to effectively bond or fix objects.

[0027] The material of the anti-corrosion layer 22 is fluoropolymer, and the bottom surface of the anti-corrosion layer 22 is bonded with an adhesive layer 23. The fluoropolymer has a certain acid and alkali resistance, and can resist the erosion of various acid and alkali solutions, and protect the adhesive material underneath it. Through the setting of the anti-corrosion layer 22, when the tape body 2 is used in a highly corrosive environment, when the protective layer 21 is corroded and damaged, the anti-corrosion layer 22 can protect the sticky material to prevent the sticky material from being corroded and causing the tape body 2 to fall off.

[0028] The material of the adhesive layer 23 is an propylene adhesive. Two waterproof layers 24 are bonded to both sides of the bottom surface of the adhesive layer 23. The propylene adhesive has good heat resistance and chemical resistance, and can maintain a certain viscosity in a high temperature environment. Through the setting of the adhesive layer 23, the adhesive layer 23 can have a certain high temperature resistance. When used in a high temperature environment, it can maintain a certain adhesion and extend the adhesion time of the object.

[0029] The material of the waterproof layer 24 is epoxy resin adhesive, and the bottom surface of the waterproof layer 24 is bonded with an anti-dust layer 25. The epoxy resin adhesive has strong water resistance and chemical stability, and is suitable for bonding and sealing in a humid environment. The epoxy resin adhesive located on both sides of the adhesive layer 23 can prevent liquid from penetrating into the interior of the adhesive layer 23. Through the setting of the waterproof layer 24, the waterproof layer 24 can play a water-blocking role on both sides of the adhesive layer 23, avoiding the liquid from penetrating into the interior of the adhesive layer 23 from both sides of the adhesive layer 23 when used in liquid, thereby causing the adhesive layer 23 to lose its adhesive effect and causing the tape body 2 to fall off.

[0030] The material of the dust-proof layer 25 is a paper film, and the contact surface between the dust-proof layer 25 and the waterproof layer 24 is coated with a layer of anti-sticking oil film. The dust-proof layer 25 is attached to the bottom of the adhesive layer 23 and the waterproof layer 24. When the tape body 2 is just peeled off, the adhesive layer 23 is protected to prevent dust from adhering to the surface of the adhesive layer 23. By setting the dust-proof layer 25, when the tape body 2 is used in an area with large dust, the adhesive layer 23 on the tape body 2 that has just been peeled off is protected to prevent dust from adhering to the adhesive layer 23, thereby reducing the viscosity and affecting the use.

[0031] The bottom surface of the dust-proof layer 25 contacts the top surface of the protective layer 21 , and both the bottom surface of the dust-proof layer 25 and the top surface of the protective layer 21 are non-sticky.

[0032] When using the polyphenylene sulfide high temperature resistant adhesive tape of the utility model, the staff will peel off the adhesive tape body 2, peel off the dust-proof layer 25 when using it in an environment with less dust, align the adhesive layer 23 with the object and stick it, and then press the protective layer 21 by hand to make the adhesive tape body 2 fit evenly on the surface of the object; when using it in an area with heavy dust, the dust-proof layer 25 is not torn off temporarily, and the dust-proof layer 25 at one end can be peeled off first, and after the adhesive tape body 2 is stuck on the object, the subsequent dust-proof layers 25 are gradually peeled off, and each peeled off section is stuck to the object, so as to prevent dust from adhering to the adhesive layer 23 and causing reduced viscosity.

[0033] The above implementation methods are only used to illustrate the embodiments of the present utility model, and are not limitations of the embodiments of the present utility model. Ordinary technicians in the relevant technical field can make various changes and modifications without departing from the spirit and scope of the embodiments of the present utility model. Therefore, all equivalent technical solutions also belong to the scope of the embodiments of the present utility model. The patent protection scope of the embodiments of the present utility model should be limited by the claims.
